@holyserpent: Yeah you're right about that, Fire Feet could be common in the new world.
If I got to choose -- it would be air because I could cause tornados to control the earth, hurricanes to control water and fire funnels to control fire. For me, air-bending is the strongest of all four.
But I think people would probably make me a fire or earth bender (Toph-style). **shrugs**
